Hello again,
let's say I have two independent polygonal objects in scene (source and destination). I need to replace geometry of destination object by the copy of geometry from source object while keeping all links, tags and attributes of destination object untouched.

Is there a way how to do that? (I don't want to make a copy of source object and delete destination object since it acts differently in undo history with other unwanted consequences. It should be treated as modification of object from cinema point of view.)
